What is the standard of automobile battery voltage?

Foreword:

Now every household has a car, automobile storage battery as an important component of automotive electrical systems, use and maintenance are what precautions it? Today, the safety net tells you what the standard voltage of the car battery is.

I believe that many car owners will find that the battery voltage will be different when driving and parking. Some voltages will become larger and some will become smaller. Is this normal? What is the reason for this? Then, the safety net introduces you to the knowledge of the use and maintenance of the car battery and the knowledge of vehicle maintenance.

First of all, the circuit in the car is composed of automobile generator-battery-various electric equipment. When the engine is turned off, only the battery supplies power to the car, and the battery voltage also follows the electricity consumption in the car (Listening to the radio, charging the electric appliance, etc.), the voltage will gradually become lower at this time. When the engine is ignited, it will start generating electricity and charge the car battery. The power generation voltage of the car will generally be higher than the battery. There is also a situation in which the speed of the generator and the car also has a certain relationship. The higher the speed, the higher the voltage, so the voltage of the battery is not always constant, so please rest assured.

So what is the standard voltage of the car battery?

The voltage of the battery in the car is about 13 volts, the load voltage is greater than 11 volts (generally at 12V-16V), and below this load voltage, the engine may not start up or start very difficult.

After the car is started, the generator starts to generate electricity. The battery voltage of the 12-volt train should be between 13.5-14.5 and the 24-volt train should be maintained at 27-29 volts.

Notice: Here we recommend the majority of car owners, if you find that the car battery has a loss, etc. must be timely battery maintenance, good maintenance can ensure your car is safer.
